I have received two text messages from someone else in my wife's text message box. She don't see them on her phone but I see them on mine. We are both on iOS 6 and she has a iPhone 4S and I have a iPhone 4.
Plus there are times she will send me a message and it will show that message and no others and then it will show all the messages but not the last one. Any ideas?

DO you think that maybe the texts are coming in from a wrong number? SOmetimes the young people send me texts that really don't even look like English, and when I ask them who they are, they realize that they were texting the wrong guy.

It has become appallingly obvious that our technology has exceeded our humanity.

Had this too, several weeks ago. Sent a picture to someone else and minutes later I got a call from someone I didn't know asking why I'd send him a picture... weird situation! I think that there's still a bug in iOS/iMessage!
